Well, its a fake trailer, but it still is really that game. It was from an "early behind the scenes look" kind of interview thing IGN did on it, so I guess its early pre-alpha type of deal. They still showed that gameplay on the IGN thing I watched and were publicising it (and from memory never in the interview made a 'the final game will look much better' type disclaimer), so I wouldn't have high expectations of the final thing looking any different or any better tbh. Its not like it was a video given to IGN that wasn't meant to be shown to the public or anything, you can go on youtube and find the interview and all that footage is spliced into the interview.

When the guy is talking about the game, it sounds like an interesting concept, but it just looks like its being executed incredibly poorly. The guy being interviewed also seems to have very little idea about the Walking Dead in general, which was a bit worrying cos I think he was one of the producers of the game. After starting off by saying they're all huge Walking Dead fans, he goes on to call Merle "Meryl" multiple times in the interview, and then at one point in the interview is talking about "These great characters that AMC have created".
